net: phy: propagate errors from default port setup

Browse source

phy_default_setup_single_port() ignores errors from phy_add_port() and
always reports success. If a PHY driver attach_mdi_port() callback fails,
the phy_port is leaked and PHY probing continues without the expected
default port.

Destroy the port and return the error.
